Bug Description

On occasion, network-manager fails to get an UMTS network connection, and quickly refuses all future attempts to use the connection. Reconfiguration of the interface (exactly the same as before) will fix it; seems like nm may mistake a transient error for a permanent one or something. Even removing the connection description from /etc/NetworkManager/system-connections and copying the exact same file back, and attempting a reconnect will fix this particular situation. (This is what I did also in this instance.)

Relevant syslog snippet around the attempt to connect to my provider, Saunalahti:
